Terminal Angle of Departure Reporting for Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current positioning methods in communication technologies require terminals to report Reference Signal Received Power (RSRP) values from multiple base stations, leading to significant resource overhead due to the need to feed back multiple RSRP values, which is inefficient.
Innovation Solution
A method where terminals measure and report angle of departure indication information from multiple network side sending devices, reducing the need to report RSRP values directly, and instead send angle of departure information, which is used by positioning devices to calculate terminal location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal reports RSRP values from multiple base stations for positioning, then the positioning measurement can be performed, but the resource overhead and signaling resources are significantly increased
Solution Approach 1:
The patent extracts only the essential positioning information (angle of departure indication information) from the complete measurement data, eliminating the need to report all RSRP values. This selective extraction reduces signaling overhead while retaining sufficient data for accurate positioning through angle-based algorithms.
Solution Approach 2:
The patent changes the reporting parameter from RSRP values to angle of departure indication information. This parameter transformation reduces the amount of data to be reported while maintaining positioning accuracy, as angle-based positioning algorithms can achieve precise location determination with fewer parameters.
2Loss of information
If the terminal feeds back multiple RSRP values for each base station, then comprehensive positioning data is obtained, but the signaling resources and processing overhead are significantly consumed
Solution Approach 1:
The patent extracts only the critical angle of departure information needed for positioning, removing redundant RSRP value reporting. This extraction approach maintains essential positioning data completeness while significantly reducing signaling processing complexity at both terminal and network side.
3Measurement precision
If the positioning server uses angle-based algorithms with multiple RSRP values, then accurate terminal location can be calculated, but the processing time and computational resources increase
Solution Approach 1:
The patent changes the input parameters for positioning calculation from multiple RSRP values to angle of departure indication information. This parameter change reduces computational complexity and processing time while maintaining terminal location accuracy through efficient angle-based positioning algorithms.
